A heat exchanger for cooling a hot process waste gas has an interior gas-flow pipe which is surrounded by a cooling jacket defined by a plurality of parallel pipe segments which are spaced from another and from the gas flow pipe. The pipe segments, through which a coolant flows, are mechanically and thermally interconnected to one another and to the gas flow pipe by means of a body of material having a thermal conductivity which is greater than that of the material from which the pipe segments are fabricated. |
